 DETAILED DESCRIPTION
FIG. 1 to FIG. 3 show a slide rail assembly 20 according to an embodiment of the present invention. The slide rail assembly 20 comprises a first rail 22, a second rail 24 movable relative to the first rail 22 along a longitudinal direction, a first releasing member 26 mounted on the second rail 24, and a limiting member 28 arranged to be corresponding to the first releasing member 26. Preferably, the first rail 22 comprises at least one blocking feature 30. In the present embodiment, the first rail 22 comprises two blocking features 30. The blocking feature 30 is located adjacent to an end of the first rail 22.
Preferably, the slide rail assembly 20 further comprises a fixed rail 32. The first rail 22 is movable relative to the fixed rail 32.
Preferably, the slide rail assembly 20 further comprises a second releasing member 34 mounted on the second rail 24.
Preferably, as shown in FIG. 1 and FIG. 4, the first releasing member 26 comprises a first end part 36 a, a second end part 36 b and an operating part 38 connected between the first end part 36 a and the second end part 36 b. The operating part 38 has at least one slot 40. In the present embodiment, the operating part 38 has two slots 40. The second rail 24 comprises a first part 42 a and a second part 42 b. A step G is formed between the first part 42 a and the second part 42 b. The first end part 36 a of the first releasing member 26 is mounted to the first part 42 a of the second rail 24. The second end part 36 b of the first releasing member 26 abuts against the second part 42 b of the second rail 24.
As shown in FIG. 4 and FIG. 5, when the second rail 24 is moved from a retracted position P0 to a first extended position P1 relative to the first rail 22 along a direction D1, the blocking feature 30 of the first rail 22 extends into the slot 40 of the operating part 38, such that the first releasing member 26 is able to abut against the blocking feature 30 of the first rail 22, in order to prevent the second rail 24 from moving further relative to the first rail 22 along the direction D1.
As shown in FIG. 6 and FIG. 7, the first releasing member 26 is operatively moved by a first force F1 from the first position L1 to the second position L2 according to the step G, such that the first releasing member 26 is disengaged from the blocking feature 30 of the first rail 22.
Preferably, the second releasing member 34 of the slide rail assembly 20 is mounted between a third part 42 c and a fourth part 42 d of the second rail 24. Wherein, a step G is also formed between the third part 42 c and the fourth part 42 d. When the second rail 24 is moved relative to the first rail 22 from the first extended position P1 to a second extended position P2, the second releasing member 34 is configured to abut against the blocking feature 30 of the first rail 22.
Preferably, as shown in FIG. 8 and FIG. 9, a through hole 44 is formed on the second rail 24 corresponding to the first releasing member 26. The limiting member 28 is arranged on the second rail 24. The limiting member 28 comprises an elastic part 46 extended along a transverse direction. When a second force F2 is applied to the limiting member 28 to drive the limiting member 28 to abut against the first releasing member 26, the first releasing member 26 is not able to be operatively moved from the first position L1 to the second position L2.
According to the above illustration, the limiting member 28 is configured to be in a free status S1 (as shown in FIG. 4 and FIG. 5) or a limiting status S2 (as shown in FIG. 8); wherein, when the limiting member 28 is in the free status S1, the first releasing member 26 is configured to be operatively moved from the first position L1 to the second position L2 (as shown in FIG. 6); when the limiting member 28 is in the limiting status S2, the first releasing member 26 is not able to be operatively moved from the first position L1 to the second position L2.
FIG. 10 to FIG. 12 show the slide rail assembly 20 applied to a chassis system 48 according to an embodiment of the present invention. The chassis system 48 comprises a first chassis 50 and a second chassis 52 detachably mounted on the first chassis 50. The second rail 24 of the slide rail assembly 20 is mounted on the first chassis 50. Wherein, the limiting member 28 is driven by the second chassis 52 to limit the first releasing member 26, such that the first releasing member 26 is not able to be pressed to move, so as to be in the status shown in FIG. 8. Wherein, when the second chassis 52 is detached from the first chassis 50, the first releasing member 26 is able to be operatively pressed to move, so as to be in the status shown in FIG. 6.
Specifically, the first chassis 50 of the chassis system 48 has an inner space 54, the first chassis 50 comprises a wall 56, and the wall 56 has an opening 58 communicated with the inner space 54. The elastic part 46 of the limiting member 28 passes through the opening 58 of the first chassis 50 to be located in the inner space 54 of the first chassis 50. Wherein, when the second chassis 52 is arranged in the inner space 54 of the first chassis 50, the limiting member 28 is moved toward to the first releasing member 26 by the second chassis 52 (such as the status shown in FIG. 8); when the second chassis 52 is detached from the first chassis 50, the first releasing member 26 is able to be operatively moved from the first position L1 to the second position L2 (such as the status shown in FIG. 6), in order to allow the first releasing member 26 to be disengaged from the blocking feature 30 of the first rail 22 at the second position L2.
Preferably, the chassis system 48 further comprises a housing 60 configured to accommodate the first chassis 50. The fixed rail 32 of the slide rail assembly 20 is configured to mount on the housing 60. The first rail 22 of the slide rail assembly 20 is movable relative to the fixed rail 32.
According to the above arrangement, the slide rail assembly 20 of the present invention is capable of allowing the first chassis 50 and the second chassis 52 to move relative to the housing 60 from the retracted position P0 (as shown in FIG. 4) to the first extended position P1 (as shown in FIG. 5). When the first chassis 50 and the second chassis 52 are at the first extended position P1, since the second chassis 52 is located in the first chassis 50, the first chassis 50 and the second chassis 52 cannot be further pulled out relative to the housing 60. In other words, when the second chassis 52 is located in the first chassis 50, the limiting member 28 is moved toward the first rail 22, so as to limit the first releasing member 26, such that the first releasing member 26 is not able to be pressed to move until the second chassis 52 is detached from the first chassis 50 (as shown in FIG. 6). Therefore, the first chassis 50 can be further moved to the second extended position P2 (as shown in FIG. 7). Thereby, the present invention allows more convenient and safer maintenance and replacement for the chassis.
Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
